Audiotonas, Martin Audio’s Lithuanian distributor, recently installed one of the manufacturer’s newest line arrays — the Wavefront Precision Compact (WPC) at Jonava Cultural Centre.

The venue, which is capable of seating almost 700 people, organises various events, which have already become annual fixtures in the calendar, such as the Midsummer Day (Joninės), contemporary art forum Homo Ludens, national festivals of choirs, street musicians, children’s pop choirs and others. Thus the demand for a good PA system was high. 

After surveying the site, Audiotonas’ sound engineers, under the project management of Vytautas Stasiukaitis, considered that eight flown elements per side of the WPC array would provide the best solution because of its optimised coverage and overall performance.

The WPC is a new breed of optimised line array featuring scalable resolution. Dependent on the number of enclosures to amp channels, the user has a scaled approach to coverage, consistency and control compared to a standard line array. For instance an optimised two-box resolution (two enclosures to one amp channel), such as that used at Jonava Cultural Centre, provides significantly improved audience coverage consistency over splay angles only, offering a compelling price and performance ratio. For low frequency extension Audiotonas specified 16 CSX118 subs which were configured for cardioid setup. “These worked perfectly as we had almost no unwanted bass at the stage,” stated Audiotonas director, Algis Sidiskis.

The system is powered by six iKON iK42 amplifiers. “The two-box resolution sounded extremely good,” said Sidiskis. “Although the venue already had benefitted from acoustic treatment, Martin Audio WPC gave much more than we expected: we programmed 3dB deviation from front to back of the venue and it averaged 95dB during shows and concerts. Any unwanted reflections were perfectly controlled, exactly as we had programmed in the DISPLAY software.”

Audiotonas’ belief in the system was quickly validated by the venue itself. “The first time I heard how impressive this Martin Audio system sounded I was pleasantly surprised,” said Jonava Cultural Centre sound engineer, Valius Strakalaitis. “The overall system intelligibility and consistency of coverage is just outstanding. I am very proud and delighted to be working with this system.”
